THE 12: #7 PLAY SINGLE-HIGH

 

WHILE the Eagles play with one Safety deeper than the other they actually play a loose version of a Cover-2 (aka Cover-2 Shell) where the Safeties drop deep and allow the CB to release their man to a Safety after a point. A lot of teams (like the Eagles) try to cheat and keep the SS nearer the line, but still dropped into a zone about 12-18 yards off the line of scrimmage. This deforms the “shell” of the Cover-2, by not keeping both Safeties on the same horizontal plane. (Sorry, this is as simple as I can explain this and it took a week to boil it down this far.)

Back when Jim Johnson was the Defensive Coordinator here he employed Brian Dawkins around the line or in a zone depending on what he wanted done. Quintin Mikell on the other hand was back deep most of the time, playing what is known as Single-High, or a Cover-1. Some teams use the Tampa-2, where the MLB drops into an underneath zone, allowing both Safeties to drop to equal depth. 

The problem with the present day Eagles quasi Cover-2 is it confuses the SS. It makes him responsible for immediate fills against the run while still maintaining coverage. This is standard SS duty, from high school to the pro’s. The caveat is that it makes him more likely to bite on fakes, which pull him out of position.

You almost never saw Q out of position and here’s why: Single-High, Cover-2, and Tampa-2 are more assignment based which keeps players from being out of position. Those coverages eliminate the guesswork and allow players to read what is happening, as opposed to re-acting to the first cue they’re shown. What the Eagles run now is an attempt to have it both ways with deep coverage AND run fills.

You see how that’s worked out.

**************************************************************************

THE MEAT:

 Here’s an experiment: Line up in front of a friend as if you’re a CB playing man-press. Have your friend release off the line. After a brief handfight, you will find yourself in what’s called the trail position (as the only way to cover him, is to follow him). This is fine, because in 15 yards you’ll release him to a Safety and— The Safety bit on a fake! You’re toast.

It’s 1-2-3.

Back when the Eagles were playing Single-High, the CB’s (Sheldon Brown, Lito Sheppard, Asante Samuel) all played with cushions that invited passes in front of them, not behind them. When we first got Man-press experts Nnamdi Asomugha and DRC, I figured the Safeties were going to a Cover-2

that would help them "bracket" and create a “Shark Tank” (that’s what I called it) of hitting, tipped passes and loose balls. Instead what we got was a deep coverage philosophy that was easy to short circuit.

 

THE MOVE:

If Man-press is no longer the way the CB’s are playing, then Single-High is the best remedy for the Secondary if we draft a FS. If we don’t draft a FS, and we head into 2013 with 2012’s starters, then we need to go to a genuine Cover-2 to cover Kurt Coleman’s lack of speed. We don’t have a MLB who can run in coverage well enough to be good at the Tampa-2. That’s not a knock on DeMeco Ryans, it’s just not his game.

The whole point is to invite passes to happen with 4 sets of eyes on them instead of just 1 (CB in a trail position). Deep coverage is a problem which doesn’t require a roster move to fix it. It would require a roster move to upgrade it and make us good or potentially dangerous; but we do have the tools to be adequate back deep. So if that FA Safety help many are praying for doesn’t come, don’t be freaked out.

  • I think we're going to see a lot of changes on the defensive side this year starting with several new faces in the starting lineup. As for the schemes we run I haven't a clue as to whats gonna happen. What you're saying make sense but it's all gonna hinge on who they bring in now that DRC and Nnamdi are all but gone.
  • All signs point to the 4-3 Under for the Front 7, but I have no idea of what the coverage base will be. My guess is it'll be a Zone-based scheme since the Front 7 will be engaged with little help to regularly give to complex coverages.

    You'll probably see the WLB drop into shallow zones so he can help out vs the run, and when the SLB isn't rushing the passer he'll stick the TE, scrape the line and do screen reads. Like the LB's in Pittsburgh.
  • Until we know who exactly will be in the secondary it would make little sense to say what king of defense they should run. The past won't be relevant unless the same guys return. It makes no sense to say, because of the past we are going to run a certain kind of defense when the likelihood of any of the previous starters returning is slim at best.

    Update: March 12, 2013
    What kind of defense they should run
  • I still say we r looking at a 3-4 front but until we see some moves in players we won't have any idea.
  • All signs point to them running a 4-3 Under like Seattle and Arizona. Here's a link:

    http://www.phillymag.com/eagles/2013/02/08/all-22-billy-davis-predators-and-the-4-3-under/

    Google "Eagles" and "4-3 Under" and and you'll see quite a bit on the subject. For some reason the staff doesn't seem to mind talking, but they just don't do it on the site.
  • We've got a new head coach and new d coordinator so there's gonna be changes. the 4-3 under make sense because the team was built for 4-3 but this coaching staff has hinted at wanting to switch to 3-4. The 4-3 under would be like a transition defense to be able to switch to 3-4 next year. This is all speculation though we really won't know anything until they get everyone together. Best guess is 4-3 under though as per billy davis
